Article
The development of support systems for surgery significantly increases the likelihood of obtaining satisfactory results. In the case of fracture reduction interventions these systems enable surgery planning, training, monitoring and assessment. They allow improvement of fracture stabilization, a minimizing of health risks and a reduction of surgery...
Article
The segmentation of fractured bone from computed tomographies (CT images) is an important process in medical visualization and simulation, because it enables such applications to use data of a specific patient. On the other hand, the labeling of fractured bone usually requires the participation of an expert. Moreover, close fragment can be joined a...
Chapter
The automation of the detection of fractured bone tissue would allow to save time in medicine. In many cases, specialists need to manually revise 2D and 3D CT images and detect bone fragments and fracture regions in order to check a fracture. The identification of bone fragments from CT images allows to remove image noise and undesirable parts and...

Several algorithms have been proposed during the past years to solve the ray-triangle intersection test. In this paper we collect the most prominent solutions and describe how to parallelize them on modern programmable graphics processing units (GPUs) by means of NVIDIA CUDA. This paper also provides a comprehensive performance analysis based on se...

Although the reconstruction of 3D models from medical images is not an easy task, there are many algorithms to perform it. However, the reconstructed models are usually large, have a lot of outliers and have not a correct topology. To interact with these models, the methods must be fast and robust. In this paper, we present an application that enab...
Article
The simulation of realistic fracture cases on geometric models representing bone structures is almost an unexplored field of research. These fractured models have several applications in computer-assisted methods that support specialist in fracture reduction interventions. For instance, the generation of specific fracture patterns can provide uncom...

Article
The use of computational techniques to help specialists in the treatment of bone injuries and diseases is widespread. These techniques usually require 3D triangle meshes representing bone fragments as input. On the one hand, bone fragments can be visualised in a more effective way. On the other hand, computer-assisted techniques are provided with m...
Article
Background and objective: The preoperative planning of bone fractures using information from CT scans increases the probability of obtaining satisfactory results, since specialists are provided with additional information before surgery. The reduction of complex bone fractures requires solving a 3D puzzle in order to place each fragment into its c...
Article
In recent years, many computational techniques have been proposed to help specialists in the fracture reduction process. This field of research is open and faces important challenges due to its intrinsic high complexity. The reduction of a complex bone fracture requires identifying the bone fragments, to estimate their proper position and to select...
Conference Paper
M-learning is gaining limelight in university education. However, its use is not widespread in the teaching of Physical Therapy. This discipline is mainly manual in nature but there are subject areas such as Electrotherapy in which the direct manipulation of an electronic device is required for a proper learning of the therapy procedures. This is o...

The identification of fractured bone from computed tomographic (CT) images is a helpful task in medical visualisation and simulation. In many cases, specialists need to manually revise 2D and 3D CT images and detect bone fragments in order to check a fracture. The automation of this process would allow them to save time. In visualisation, it allows...
Conference Paper
Visualization and interaction with 3D bone models reconstructed from medical images are fundamental for biomedical applications. They are useful for surgeons in order to diagnose and plan surgical operations. Although traditional reconstruction techniques based on isosurfacing are mainly used for visualization, it is desirable to obtain labelled mo...
Chapter
Medical image processing and reconstruction of three-dimensional models are fundamental for bio-medical applications. Although traditional reconstruction techniques based on iso-surfacing are mainly used for visualization, it is desirable to obtain labelled models in order to enable their integration into interactive environments. Therefore, in...
Chapter
The identification of bone tissue from computed tomographies (CT images) is a key procedure in medical visualization and simulation because it allows to adapt both processes to the anatomy of a specific patient. On the other hand, the identification of fractured bone adds some constraints and usually requires the participation of an expert. This is...
Conference Paper
Surface reconstruction from 3D medical images is fundamental for bio-medical applications. Nevertheless, the generation of valid geometric surfaces is a difficult task due to the complexity of the structures necessary to represent the human body. In this paper, we describe the main strategies concerning surface reconstruction and planar contour ext...
Conference Paper
Many computer interactive environments require to calculate collision detections between geometrical models, usually triangle meshes. In this paper, a comparative study of some collision detection strategies is realized. For this purpose, the compared algorithms have been implemented. Some of these algorithms also allow realizing other procedures,...
Conference Paper
Boolean operations are complex, so it is difficult to perform them in real time. Sometimes, the goal is only to reconstruct the model. In that case, accuracy is not too important and other approaches can be performed. However, the reconstruction of the model must satisfy some requirements like smoothness or velocity. In this paper, a method to reco...
Conference Paper
In this paper, a method to repair the meniscus virtually using sensory devices is presented. Meniscus operations using arthroscopy techniques require great skill by the surgeon because he cannot see the area of the operation directly. The surgeon only has the visual information that a monitor provides as well as the tactile information that he gets...
Article
Full-text available
The use of hierarchical spatial decomposition in 3D scenes in order to manage the complexity of the objects is a well known approach. The main problem with this technique is the updating process when the mesh is modified. Any deformation or rotation means a new complete reconstruction of the structure. By other way remeshing techniques modify the s...

Fracturing of geometric models is an open and growing field in computer graphics. This project aims the development of new techniques and algorithms that simulate the fracture of geometric models representing bones using patterns previously obtained by mechanics experiments, and eventually incorporate physical aspects to the geometric models.
